nio做客户端是否是bug？？？？在线等

客户端事件处理线程代码如下：

while (!bStop) {
      try {
        int n = selector.select();

// 如果要shutdown，关闭selector退出
        if (bStop) {
          selector.close();
          break;
        }

// 如果select返回大于0，处理事件
        if (n > 0) {
          for (Iterator i = selector.selectedKeys().iterator(); i.hasNext(); ) {
            // 得到下一个Key
            SelectionKey sk = (SelectionKey) i.next();
            i.remove();

// 处理
            if (sk.isConnectable()) {
              this.event.processConnect(sk);              
            }
            else if (sk.isReadable()) {
              this.event.processRead(sk);
              sk.cancel();
            }
            else if (sk.isWritable()) {
              this.event.processWrite(sk);
              sk.cancel();
            }
          }
        }
        else {
          //?????注册write后，不停的执行
        }
      }
      catch (IOException e) {
        log.error(e.getMessage());
        this.event.processError(e);
      }
      catch (Exception e) {
        log.error("数据处理错误: " + e.getMessage());
      }
    }
    log.debug("nio监听线程已经退出");
  }
代码流程如上，当我注册write时，selector不停的返回0,这是否是个bug,我觉得如果有在连接或当selector返回值为0时注册一个write，就只有当我write时，事件才会触发，这是不是nio的一个bug
